Abstract

An apparatus is proposed for mixing and processing free-flowing materials, especially moulding sand, having a cylindrical mixing vessel (1), the mixing vessel (1) including its bottom and cover being arranged so as to be stationary and one or more rotating whirler shafts (7) are provided which revolve in the vessel on a circular trajectory. …<IMAGE>…

Description

Vynález se týká zařízení pro míšení a úpravu sypkých ma· teriálů,· zejména s válcovým mísícím bubnem.BACKGROUND OF THE INVENTION The invention relates to an apparatus for mixing and treating bulk materials, in particular with a cylindrical mixing drum.

Dosavadní stav technikyBACKGROUND OF THE INVENTION

Jsou známy míchačky opatřené míchacími hřídely a rameny která vsak neobíhají, nýbrž jsou uložena nehybně. Pro přivádění míšeného materiálu k míchacím elementům je buďto a/ dno míchačky upraveno otočně, což přináší podstatné problémy s utěsněním rotujícího dna míchačky oproti nepohyblivým stěnám míchačky, přičemž také uspořádání vyprazdňovacích 2áklopek je při tomto provedení problematické, nebo b/ celý míchací buben je upraven otáčivě při nehybném uspořádání míchacích elementů. Tato varianta je zejména známá ze spisu DE-OS 33 12 861 Al.Agitators are known which are provided with agitator shafts and arms which, however, do not circulate but are stationary. For supplying the mixed material to the mixing elements, either the a / mixer bottom is rotatable, which presents significant problems with sealing the rotating mixer bottom against the stationary mixer walls, and the arrangement of the emptying flaps is also problematic in this embodiment, or with the stationary arrangement of the mixing elements. This variant is particularly known from DE-OS 33 12 861 A1.

Také toto řešeni vyžaduje komplikované a poruchové uspořádání pokud jde o vyprazdňovací záklopku a utěsnění vrchních částí míchačky oproti rotujícímu míchacímu bubnu.This solution also requires a complicated and breakdown arrangement with respect to the discharge valve and the sealing of the upper parts of the mixer against the rotating mixing drum.

Podstata vynále_zu . .SUMMARY OF THE INVENTION. .

Předložený vynález si klade za úkol odstranit uvedené nevýhody a vytvořit míchačku, která je jednoduchá, levná při výrobě a bezproblémová v provozu. Současně má pomocí spolupůsobení otáčivé radlice s rovněž otáčivým obíhajícím míchacím hřídelem dosáhnout optimálního promísení míšeného materiálu.It is an object of the present invention to overcome these disadvantages and to provide a mixer that is simple, inexpensive to manufacture and hassle-free in operation. At the same time, the interaction of the rotating blade with the rotating mixing shaft should also achieve optimum mixing of the material to be mixed.

- 2 Podstata vynálezu spočívá v tom, že míchací buben včetně jeho dna a víka je uspořádán nehybně s v něm je upraven jeden nebo více rotujících míchacích hřídelů, které v bubnu obíhají po kruhové dráze a ve stejném smyslu se v bubnu otáčivě pohy-. buje jedna nebo více radlic.The principle of the invention is that the mixing drum, including its bottom and lid, is immovably disposed therein, one or more rotating mixing shafts, which circulate in a circular path in the drum and rotate in the drum in the same sense. one or more plowshares are in production.

Rotační a obíhavý pohyb míchacího hřídele a radlice je zajišlován pomocí převodů a jedním společným nebo dvěma motoryvRotary and orbital movement of mixing shaft and blade is provided by gears and one common or two motors

Příklad 'provedení vynálezuAn embodiment of the invention

Zařízení podle obr. 1 a 2 sestává z míchacího bubnu 1, v jehož víku a dně jsou upraveny plnicí klapka 2 a vyprazdňovací záklopka 2· Ve skříni na víku míchacího bubnu 1 je uložen pře- » vod ,4 středního hřídele 8 poháněný motorem jj. Rotující střední hřídel 8 unáší sebou převod $ míchacího hřídele 7 spolu s tímto míchacím hřídele 7 a na svém spodním konci též radlici 9, {The device according to FIGS. 1 and 2 consists of a mixing drum 1, in whose lid and bottom are provided a filling flap 2 and a discharge valve 2. In the housing on the lid of the mixing drum 1 there is a transmission 4 of the central shaft 8 driven by the motor. The rotating central shaft 8 carries with it the gear shaft 7 of the mixing shaft 7, along with this mixing shaft 7, and at its lower end also the blade 9, {
